I know the Q701 have an impedance of only 62 ohms, but the normal gain setting on the STX just doesn't cut it for me. I can crank the volume to 100% and it still sounds a bit weak. On the high gain setting, 30% is uncomfortable loud. Is it just a bad amp match? I didn't have this problem with the Fiio E9, which from what I've read is about equivalent to the STX amp.
Sennheiser HD 598 gets uncomfortably loud around 50% volume normal gain, and ATH M50 doesn't go above 33% volume without being too loud. Just thought I'd include that information.
Will using the High Gain setting damage the headphones, or cause any sort of distortion?
